Positive Progress with the feasibility study on the Molyhil Tungsten and Molybdenum Project in the NT

Dated: 12 October 2011

The Directors of Thor Mining PLC ("Thor" or the "Company") (AIM, ASX: THR, THRO) the Australian gold, tungsten and molybdenum explorer and developer, are pleased to announce that they have received the initial findings of the definitive feasibility study ("DFS") on the Molyhil tungsten and molybdenum project in Australia's Northern Territory ("Molyhil") and that these underline the economic rationale for the development of Molyhil.

Highlights

·           Estimate based on Pit Phase 1 of 1.4 million tonnes of ore;

·          Potential cash operating margins of A$98/tonne of ore processed;

·           Capital expenditure estimate of A$66million;

·           Revised ore reserve and mining plan in progress; and

·          DFS now estimated to be completed during November 2011.

Commenting on the publishing of the initial findings of the DFS, the Chairman of Thor, Mr Mick Billing, said today:

"These are very positive early outcomes and provide us with a great deal of confidence in the results of the feasibility study.  While much more work is required, these cost estimates, along with current metal prices, are key to the study outcome.

The improving commodity price for tungsten, in particular, has added value to Molyhil, and the medium term prospects for tungsten are positive.

The DFS has been undertaken by the leading Australasian engineering firm, Proteus EPCM Engineers ("Proteus"), which has completed an estimate of capital & operating costs for the proposed mining and processing operation at Molyhil.

Key outcomes of the costs estimates include:

·     Capital costs ·	A$66 million including contingency
·     Operating costs ·	A$79/tonne of ore mined and processed
·     Annual throughput of ore ·	400,000 tonnes per annum

Revenue assumptions

·     Revenue	A$177/tonne of ore mined and processed
·     Tonnes of ore mined and processed	1.4 million tonnes ("Pit Phase 1")
·     Tungsten grade (WO3)	0.60%
·     Tungsten price (APT)	US$460/mtu - discounted by 23%
·     Molybdenum grade (MoS2)	0.13%
·     Molybdenum price	US$15.00/lb - discounted by 12%
·     Exchange rate	A$1:00 = US$0:95

Other potential enhancements to the project include up to 100,000 tonnes per annum of high grade magnetite which will be mined and extracted as part of the process of producing tungsten and molybdenum concentrates. The value of any contribution from this commodity is still being assessed.

Next Steps

The next phase of this DFS involves re-estimating the ore reserve, including use of the above calculated parameters and preparation of a new mining plan for Molyhil. The outcome of this work has some potential to vary both the total tonnage of ore to be mined from Pit Phase 1 and also the grade of that ore.

Following these steps the Molyhil financial model will be updated to reflect all the revisions to operating parameters.

The final results of this DFS are now expected to be completed in November 2011.

About Molyhil

Molyhil lies in the centre of Australia, 220 kilometres North East of Alice Springs. The geology consists of a well-defined lode which is a magnetite skarn in granite. The mineralogy is fairly simple with scheelite and molybdenite. The lodes dip steeply east and the body of mineralisation is open down plunge to the south. The results of a definitive feasibility study unveiled in 2007 confirmed the viability of a 400,000 tonnes per annum mining and processing operation with attractive financial outcomes.
